It depends. Y can hit harder and works well in doubles and singles. X has a better movepool to work with but won’t do as well in doubles. Also x has more weaknesses even though stealth rock is only 25% damage

I prefer Y over X but overall it just depends on what your team needs. Judging from your team, Y is probably the better option
